Today, we are going to take a look at the Optronics 4 way and 5 way Flat Trailer Harness Plug Protector. Now this is going to be a quick and easy way to protect the four or five pole wiring on your trailer. A lot of times those can get banged around especially if you are using them for a long time or they're in frequent use.This is just going to go over our bare terminals on that trailer end wiring and then it's also going to have a small plastic post that is going to fit into the open port for our ground on our wiring. So here we have a four pole. This also, again, works with five pole, it just has the extra terminal on the one side which our plug is built for and it just matches right up. Fits inside there, fits really snug and then you would just have this attached to say the coupler on your trailer or maybe the tongue, just anywhere where you would want this wiring to be secured and out of the way.This is going to keep any debris from building up inside those terminals on your wiring or any water build up or anything like that.

And it's going to keep that wiring from getting corroded or kind of gunked up and it's also going to keep it from getting banged around on the ground or impacted with anything. It's just going to keep it nice and up and out of the way.Now this does not come with any hardware to get that attached so you will have to pick up a self tapping screw or whatever hardware you'd like to use, maybe a nut and a bolt but you will have to provide that on you own. The mounting hole is going to be about 3/16th of an inch in diameter, overall the connector is going to be about an inch and a half wide by about an inch and a quarter tall and at the widest point where it sort of bows out for our mounting location, that's going to be about half an inch. So it's really going to be about the same size as the connector on your wiring. It's pretty comparable there.All in all, it's just going to be quick and easy way to improve the longevity of your wiring on your trailer and keep everything working as it should.

It's not a bad idea to maybe put a little bit of dialectic grease in those terminals so that it'll keep the grease on your plug as well. If you don't have any of that, we do sell dialectic grease here at Etrailer.com if you want to pick some up.And that's going to do it for our look at the Optronics 4 and 5 way Flat Trailer Harness Plug Protector.

I had lost my old cover. This product fit perfect
and it arrived quickly.
It keeps dirt out of the contacts.
The hole allows you to put a cable to hold it to vehicle so when you take it off you don’t loose it.

Raised area around mount hole provides clearance for plug from mounting surface. It doesn't retain the plug very tightly, and only by the pins. It is for use while trailer is parked. The plug won't just fall out, but brushing the hanging pigtail can pull it. Be sure to seat the plug completely.

Good tight fit. I use the hole to run a plastic cable tie through to fasten the cap back onto the harness. This way it will never get separated and lost.
